VPN Results

[chadw]

I have never setup a VPN. I have Terminal Services setup for one remote employee. I was wondering if a VPN will better serve the company. I have heard that VPN are very slow. I have a pix515 and I didn't know what ports to open and if it was hard to establish a connection on the server side. What is all involved? What are the Pros and Cons of a VPN?

Can anyone help me out here?

Thank you,

Chad

Which ports need to be opened for running VPN

A: PPTP VPN uses TCP Port 1723, IP Protocol 47 (GRE); L2TP: UDP Port 1701; IPSec: Pass protocol 50 and 51. Note: 47 is a protocol number and not TCP port. The protocol name is GRE. It'll make a big difference when configuring your firewall or router.

What statements are required to allow a VPN inbound past my Cisco PIX?

The following example is a simple PPTP access list:

access-list 110 permit tcp any host x.x.x.x eq 1723
access-list 110 permit gre any host x.x.x.x
